If it's just a mobile home & no land, then Bank of the West would be an option. If the home is attached to the ground then you can try American Financial Resourses. They do FHA loans for manufactured housing. http://www.afrwholesale.com.
US Bank may be able to help, not a lot of lenders to choose from. If the property is owner occupied you may find a lender who can provide an FHA loan. With a 20% down payment on an owner occupied a Fannie Mae lender. These options assume on land and owner occupied. Investment and second homes are left to the Hard Money lenders. Good Luck
